Kev Sib Tham:
Qhov txawv ntawm lub thav duab beam thiab lub thav duab truss feem ntau yog nyob rau hauv qhov kev faib khoom thiab cov qauv. Lub thav duab beam feem ntau muaj cov ncej kab rov tav txhawb nqa los ntawm cov kem ntsug, nrog rau qhov thauj khoom xa mus rau cov kem ncaj qha. Qhov no ua rau nws zoo heev rau luv luv mus rau nruab nrab.
Ntawm qhov tod tes, lub thav duab truss muaj cov khoom peb ceg sib koom ua ke. Qhov zoo tshaj plaws ntawm lub truss yog nws lub peev xwm los xa cov zog axial (tsis yog khoov) los ntawm cov ntsiab lus, uas ua rau nws ua haujlwm tau zoo rau qhov ntev dua thiab feem ntau siv rau hauv cov qauv uas xav tau kev txhawb nqa tsawg tab sis npog thaj chaw loj, xws li lub ru tsev Hoobkas lossis cov choj ntev.
Lo Lus Nug 2: Kev Tshawb Fawb Yooj Yim
Lo lus nug: Ib lub choj siv lub cev truss peb ceg. Piav qhia txog qhov zoo ntawm kev siv lub cev truss rau lub choj.
Kev Sib Tham:
Cov thav duab truss muaj ntau qhov zoo thaum siv rau hauv cov qauv choj:
1. Lub zog thiab kev ruaj khov:
- Cov ntsiab lus uas tsim cov duab peb ceg hauv lub thav duab truss ruaj khov heev thiab muab kev faib khoom sib npaug.
2. Kev Siv Khoom Zoo:
- Lub peev xwm hloov pauv axial tso cai rau kev siv cov khoom sib dua yam tsis muaj kev txo qis lub zog. Qhov no tuaj yeem txo cov nqi khoom siv tag nrho.
3. Kev Tsim Qauv Yooj Yim:
- Cov Trusses tuaj yeem hloov kho rau ntau yam kev teeb tsa (xws li Howe, Pratt, Warren Truss), uas tuaj yeem hloov kho rau kev tsim qauv thiab kev xav tau zoo nkauj.
4. Ntev Ntau:
- Cov trusses muaj peev xwm nthuav dav mus deb dua yam tsis tas yuav muaj ntau qhov chaw txhawb nqa, uas zoo tagnrho rau cov choj thiab lwm qhov loj.
Lo Lus Nug 3: Kev Kawm Txog Kev Siv
Lo lus nug: Tshuaj xyuas hom thav duab uas tsim nyog tshaj plaws los siv los tsim lub chaw ua si niaj hnub thiab muaj peev xwm loj.
Kev Sib Tham:
Rau cov chaw ua si niaj hnub uas muaj peev xwm loj, lub thav duab chaw dav dav yuav yog qhov kev xaiv zoo tshaj plaws. Qee qhov laj thawj rau kev xaiv lub thav duab chaw dav dav yog:
- Kev Faib Khoom Peb-Seem:
Cov thav duab chaw muaj peev xwm xa cov khoom thauj los ntawm txhua qhov kev taw qhia, uas yog qhov tshwj xeeb tshaj yog rau cov qauv loj uas yuav tsum txhawb nqa cov ru tsev dav.
- Tsim Qauv:
Cov thav duab chaw yog sib sau ua ke los ntawm cov khoom siv modular uas tuaj yeem tsim ntau thiab teeb tsa sai sai rau ntawm qhov chaw, txo lub sijhawm tsim kho thiab cov nqi.
- Kev Zoo Nkauj thiab Kev Ua Haujlwm:
Cov qauv thav duab chaw muab kev ywj pheej ntawm kev tsim vaj tsev thiab tuaj yeem muab qhov zoo li yav tom ntej, tsim nyog heev rau cov chaw ua si uas kuj ua lub cim ntawm kev tsim vaj tsev.
Kev kaw
Kev nkag siab zoo txog cov hom thav duab thiab lawv cov ntawv thov yog qhov tseem ceeb hauv kev tsim kho thiab kev tsim kho. Cov thav duab tsis yog tsuas yog muab cov qauv rau kev tsim kho xwb tab sis kuj txiav txim siab qhov ua tau zoo, kev ruaj khov, kev zoo nkauj, thiab kev lag luam ntawm qhov project. Hauv lub ntiaj teb uas tsom mus rau kev tsim kho kom zoo thiab ruaj khov, kev siv cov tswv yim thav duab kom raug yuav txuas ntxiv mus ua qhov tseem ceeb rau cov engineers thiab architects thoob ntiaj teb.
Thaum kawg, lub peev xwm los tshuaj xyuas cov kev xav tau ntawm cov qauv thiab xaiv hom kev teeb tsa kom haum yuav yog qhov tseem ceeb rau kev tsim cov tsev thiab cov khoom siv uas muaj kev nyab xeeb, ua haujlwm tau zoo, thiab ruaj khov. Vam tias, tsab xov xwm no tau muab cov kev nkag siab zoo thiab ua rau koj paub ntau ntxiv txog ntau hom kev teeb tsa hauv cov ntsiab lus ntawm kev tsim kho vaj tse thiab kev siv tshuab.
